bit of a rough time getting this to work and its an understanding piece on my end... If i have a spinner item that contains the text "The [item] is [color]" and upon selecting this, I would like it to populate a... tablerow or something like that(or just a relativelayout)... with buttons and there would be two buttons, [item] and [color], stacked one on the other. <pre><code>public void onItemSelected(AdapterView<?> parentview, View arg1, int position, long id) { final TableLayout t1 = (TableLayout)findViewById(R.id.button_items); final TableRow tr = new TableRow(t1.getContext()); ArrayList<String> words = Create_ArrayList(R.raw.titles); </code></pre> // Create_ArrayList just parses known words like the [item] and [color] items and puts them into an array... for enumeration purposes later on. <pre><code>String sentence = (String) spin.getSelectedItem(); if(sentence.contains("[item]")) { String line = words.get(1); ArrayList<String> x = getParts(line); </code></pre> //arraylist should just be [item] and [color] at this point... <pre><code> Toast.makeText(getBaseContext(), Integer.toString(x.size()), Toast.LENGTH_SHORT).show(); for(int i = 0; i<x.size(); i++) { Toast.makeText(getBaseContext(), x.get(i), Toast.LENGTH_LONG).show(); Button btn = new Button(tr.getContext()); btn.setText(x.get(i)); btn.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); tr.addView(btn); t1.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); } } } </code></pre> but i keep getting... <pre><code>java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first </code></pre> and the buttons dont show up... app just crashes... into a mountain. help is much appreciated... Thanks all!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
